White House taps ARPA-E to boost methane detection

Frank Tittel, the J.S. Abercrombie Professor in Electrical and
Computer Engineering and Professor of Bioengineering, and his group have
created a highly sensitive portable sensor that tests the air for damaging
greenhouse gases. The sensor is mentioned as a possible solution to the EPA’s
missing methane problem. IEEE Spectrum: http://bit.ly/1scmV9x
